The Slick Side A1 Upper eliminates the shell deflector and forward assist.
Charging handle and components sold separately.
All points where other parts attach are finished current mil-spec dimensions. Current production AR-15 components will fit perfectly.
Note that the AR-15 / M16 Slick-side Upper Receiver is period-accurate therefore it DOES NOT have M4-type feed ramps found on most current-production AR-15 flattop upper receivers.
